I found it by guess, I knew that logs were in "/var/log" and opened
"syslog.1" thinking it was a system issue.

this is the point when I closed Mythtv FE for the night (which normally

The first time the freeze-up happened I was in the BE set-up and got called
away, when I returned it was unresponsive, and only came back after a hard
